论以健康的声音抒惰

歌唱不仅是声音艺术,也是情感艺术。一个健康动听的声音来自于科学的呼吸,机音管道的建立,声音触点精巧的碰撞和歌唱心理的稳定。如要准确贴切表达歌曲的主题和内容,必须把感情融入歌声之中。一个歌者对生活体验的越深刻,对生活越理解,就会对情感的把握越有分寸,就能使歌声与情感相贴切和相融,才能达到以健康的声音抒情。     

Cultural and Status Differences in Intergroup Conflict Resolution: A Longitudinal Study of a Middle East Dialogue Group in the United States

Supporters of the contact hypothesis have arguedthat positive intergroup contact is facilitated whenparticipants have equal status with one another.However, the exact dimensions of equal status are often unclear, having been defined variously as equaloccupational status, having close friends of anotherrace, or having equal roles in the contact situation.This paper argues that cultural differences between groups must be taken into account, particularlywhen intergroup contact occurs in formal conflictresolution exercises. Non-Western participants will beat a disadvantage when attempting to find common ground with Western participants in conflictresolution exercises based on Western culturalpractices. Based on a 6-year participant observationstudy of a Palestinian-Jewish dialogue group, this paper argues that familiarity and expertise in usingthe culture-based rules of interaction play an importantbut often subtle role in intergroup conflict resolution.Participants must have some basic equality in their ability to function within thedominant culture.     

Stand Up for Health: Programme theory for an intervention to reduce sedentary behaviour in contact centres

BackgroundContact centre staff spend up to 95 % of their day seated, which can lead to a range of negative health outcomes. The aim of this study was to develop a programme theory for a complex intervention to reduce sedentary behaviour in contact centres.MethodsThe 6SQuID model was used. A literature review, and focus groups at one contact centre were used to: understand the problem (step 1); identify modifiable factors (step 2); and develop a theory of change (step 3). A workshop shaped a theory of action (step 4), and the programme theory was refined after testing activities over 6 months (step 5). The intervention is currently undergoing further evaluation and feasibility testing in a larger scale stepped wedge randomised controlled study in 11 contact centres (Step 6).ResultsStep 1: Limited opportunity to sit less, and move more at work was identified as the main problem. Step 2: Modifiable factors were identified at four levels of the centre. Step 3: A theory of change was developed around cultural norms and individual behaviour change. Step 4: Actions were developed to ‘activate’ the theory of change. Step 5: Activities were implemented, and adapted over 6 months and the programme theory was refined.ConclusionThe programme theory behind this intervention is robust, evidence based, adaptive and transferable.     

Monetary incentives,motivational orientation and affective commitment in contact centers. A multilevel mediation model

High quality contact and customer relationships are key services for all types of firms. To achieve this high quality performance standard, companies need highly motivated and committed employees, and human resources managers are responsible for designing and implementing practices capable of satisfying both economic exchanges and social exchanges in employee-organization relationships. The aim of this study is to analyze the relationships between monetary incentive expectation and affective commitment, in addition to the mediating role of motivation orientation in this relationship, in contact center employees. In particular, based on the social exchange theory (Blau, 1964), the social exchange model of Cropanzano and Mitchell (2005), and the self-determination theory (Deci, Olafsen, & Ryan, 2017), our study adopts a multilevel perspective to examine these relationships in a sample of 2367 contact center employees from 297 teams (3 or more members). The results showed that the level of performance-contingent rewards (team-level) guides the team’s autonomous motivation (team-level), which, in turn, fosters employees’ affective commitment (individual-level). The results have practical implications for human resource managers and for interventions aimed to promote contact center employees’ affective commitment, taking performance-contingent rewards into account.     

社会资本对受雇就业农民工职业地位获得的作用

本文以空位竞争模型中对劳动力市场中工作结构与奖励结构的假定为基础,进一步地在理论上推演出了社会资本对农民工职业地位获得作用的假设。对实地调查数据的分析发现:尽管职业流动的频率越高越不利于农民工获得专业技术或管理等较高职业地位,但对于社会关系的广度高的个体,职业流动频率对职业地位的晋升具有正向作用。该结果意味着职业流动频率高并不一定不利于农民工职业地位的获得,在缺乏社会关系广度下的频繁职业流动才是导致农民工水平职业流动的原因。     

Carers and Professionals' Perspectives on Foster Care Outcomes: The Role of Contact

This study investigates the association between the contact of children or young people in care with their family, and the foster care placement evaluation (positive or negative) in Portugal. According to the perspectives of foster carers and service professionals' perceptions regarding children and young people's reactions, during and after the visits, are measured. Utilizing a quantitative approach, two fostering services teams and 140 foster carers completed questionnaires, which had 212 children in common. Results indicated that despite the importance of continued contact, especially for children and their parents, it was not determined to be essential to long-term placement. On one hand, there was the perception that a high percentage of children expressed positive reactions during and after the visit, while on the other hand, this didn't influence the perception of placement success. This study also showed significant differences between foster carers' and the professionals' perceptions on several dimensions of foster care, especially the children's reactions during visits. These differences need to be further analyzed in future research and the outcomes used to help improve contact management.     

Redress and Corporate Human Rights Harms: An Analysis of New Governance and the POSCO Odisha Project

Human rights harms caused by transnational business in the global South are increasingly being addressed using ‘new governance’ tools and their cooperative problem-solving processes. Such an approach is employed by OECD National Contact Points (NCPs), which received a complaint regarding Korean steel giant POSCO in India. This article explains the contested aspects of the POSCO project in its politico-economic context and shows how the NCP process sacrificed elements essential to an effective new governance approach. This case highlights the challenges facing new governance tools in advancing human rights in the global South raising significant questions about their usefulness in this context.     

Egocentric contact networks in comparison: Taiwan and Hungary

This study compares the size and structure of egocentric networks in Taiwan and Hungary using a diary approach. Both countries have transformed from authoritarian regimes to democratic states, yet they differ in social, economic, and cultural institutions that may be common to the respective larger region where each is located. To sample the structure of each egocentric network, we extracted information from largely identical contact diaries collected in both countries, 51 from Taiwan and 138 from Hungary. After comparing sample characteristics, network size, and composition, we construct a Strength of Ties (SoT) index based on two objective and two subjective measures of ego-alter ties. We then use this index to analyze tie strength by the types of relationships. On average, the number of alters contacted in one week is much larger in Taiwan than in Hungary, and the gap remains unchanged after controlling for key socio-demographic background factors. Even though the four indicators that we use to construct the SoT index are distributed similarly among the respondents in both Taiwan and Hungary, the composite index pinpoints how the types of relationships play somewhat different roles across the nations. The findings imply that the tendency to maintain only the closest ties with kin and other close friends is linked to distrust in others, a possible ill effect lingering from the authoritarian past. The implication is partially supported by further analyses using the ISSP 2006 survey data. We address how our findings may contribute to the existing literature on the linkage between societal characteristics and interpersonal ties.     

Critical Review and Uncertainty Analysis of Factors Influencing Influenza Transmission

Influenza remains a significant threat to public health, yet there is significant uncertainty about the routes of influenza transmission from an infectious source through the environment to a receptor, and their relative risks. Herein, data pertaining to factors that influence the environmental mediation of influenza transmission are critically reviewed, including: frequency, magnitude and size distribution and virus expiration, inactivation rates, environmental and self‐contact rates, and viral transfer efficiencies during contacts. Where appropriate, two‐stage Monte Carlo uncertainty analysis is used to characterize variability and uncertainty in the reported data. Significant uncertainties are present in most factors, due to: limitations in instrumentation or study realism; lack of documentation of data variability; or lack of study. These analyses, and future experimental work, will improve parameterization of influenza transmission and risk models, facilitating more robust characterization of the magnitude and uncertainty in infection risk.
